PLOW.

Specification of Letters Patent.

Patented Mar. '7, 1911.

Application filed April 23, 1910. Serial No. 557,200.

To all whom it may concern;

lie it known that I, Go'rrrarno d' ENGER, i

a citizen of the United States, residing at Silica, in the county ofRandolph and State of lVest Virginia, have invented new and usefulImprovements in Plows, of which the following is a specification.

The present invention appertains to plows, the purpose being to devise anovel structure of beam for receiving a spring actuated clevis and acolter, the latter being adjustable in pitch to adapt the same to thenature of the work in hand.

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in the ac companying drawing, and pointed out inthe appended claim.

Referring to the drawing, forming a part of the specification, Figure lis a side view of a plow embodying the invention. Fig. 2 is a top planview thereof. Fig. 3 is a horizontal section on the line 38 of Fig. 1.Fig. 4 is a section of the draft bar on the line 4-4 of Fig. 2, showingthe end of the beam in which the draft bar is supported.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawing, by the samereference characters.

The beam 1 in its specific construction is formed of a bar of suitablelength doubled upon itself and having the rear ends bent downwardly toform a standard 2, which is provided at its lower end with a shovelblade 3 of any form. The bar at the fold is spread to provide a loop 4,which receives a draft bar 5, the latter being of square form in crosssection, as indicated in Fig. i. The

outer end of the loop is widened. opposite the opening formed thereinthrough which the draft bar 5 passes. The outer; end of the draft barhas a sleeve (3, which receives a pin by means of which the clevis 7 isconnected thereto so as to swing vertically about a horizontal axis. Ahelical spring 8 of the expansible type is mounted upon the draft bar 5and is confined between the front end of the loop 4 and a stop 9adjustably mounted upon the rear end of the draftbanthereby admitting ofthe tension of the spring 8 being regulated. The rear portion of thedraft bar 5 is made rounding and threaded to receive the stop 9, whichconsists of a nut.

The folded portions of the bar are brought together in the rear of theloop at and near their rear ends are crimped to form a second loop 10,which receives the upper end of the colter 11. The rear portions of thefolded parts forming the standard 2 are outwardly crimped, as indicatedat 12, to provide a space through which passes a rod 13', the front endof which is forked to embrace opposite sides of the colter 11 to whichthey are connected by means of a fastening 14. passing throughtransversely alined openings formed in the members of the fork and thecolter. The rear portion of the rod 18 is threaded and receives a handnut 15, which draws the colter with its lower end close against theshovel blade 3.

Handle bars 16 are secured at their lower ends to opposite sides of thebeam 1 and are supported by means of braces 17, which are pivoted attheir lower ends to the rear portion of the beam and have adjustableconnection at their upper ends with the handle bars.

The colter 11 consists of a bar having its front portion sharpened so asto cut through roots, turf and sod. The upper end of the colter issupported in the loop 1O of the beam and is secured therein by means ofa wedge 18. The lower end of the colter touches the shovel blade 3 andis held in place by the rod 13, the latter being tightened by means ofthe hand nut 15.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichi now consider to be the embodiment there of, l desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimappended hereto.

Having thus described the invention what is claimed as new, is:-

In an implement of the character specified, a bar doubled upon itselfand having folded portions brought together and touching approximatelythroughout their extent, said folded bar constituting a beam and havingits rear portion curved downwardly to form a standard and said barhaving registering portions of the folded parts curved outwardly intocrinips which form a series of openings, one opening at the front end ofthe beam, at second opening near the rear end of the beam, and a thirdopening extending horizontally through the standard at a point betweenthe upper and lower ends thereot, substantially as and for the purposespecified. 10

In testimony whereof I affix my signature in presence of two Witnesses.
